猫薄荷为何让猫“疯狂”?

猫薄荷为何让猫“疯狂”?Why Does Catnip Make Cats Go Crazy?文本难度:考研刘立军供稿Of the many bewildering behaviors cats display, one of the strangest is their obsession with a specific species of plant. After just one whiff, even the most stoic cat can start pawing, drooling, biting, and wriggling in a state of pure feline euphoria. So, why do cats go crazy for catnip? This is the question cat behavior expert Masao Miyazaki and chemist Toshio Nishikawa set out to answer in 2013. Along with their research teams from Iwate and Nagoya University, they began by studying silvervine – a plant that sparks a similar response to catnip.猫咪有着许多令人费解的行为,其中最奇特的莫过于对某一特定植物的痴迷。即便是最冷静自持的猫,哪怕只是闻上一口,也会瞬间陷入抓挠、流口水、啃咬、翻滚的状态,沉浸在纯粹的猫咪欢愉中。那么,猫咪究竟为什么会为猫薄荷神魂颠倒?2013年,猫咪行为学家宫崎正夫与化学家西川俊夫便带着这一问题展开了研究。他们与来自岩手大学与名古屋大学的研究团队携手,先从木天蓼这种植物入手——这是一种同样能在猫身上引发和猫薄荷相似反应的植物。First, the researchers painstakingly extracted chemical compounds from the plant and dribbled various combinations of them onto filter paper. Then they brought in some cats and studied which compounds they were drawn to. Overwhelmingly, their feline testers pounced on the papers containing nepetalactol. And when Miyazaki and his student Reiko Uenoyama ran blood tests on the cats who’d interacted with nepetalactol, they found their systems were flooded with endorphins. These hormones block pain signals, relieve stress, and generally create a happy, calming effect. And catnip triggers the same endorphin rush with a similar chemical called nepetalactone, and it’s this flood of happy hormones that gives catnip and silvervine their signature drug-like response.研究人员先是费尽心力,从木天蓼中提取各类化合物,再把不同配比的提取物滴在滤纸上。随后,他们找来猫咪,观察哪些化学成分会吸引它们。结果显而易见,绝大多数受试猫咪都径直扑向含有荆芥内酯醇(nepetalactol)的滤纸。宫崎正夫和他的学生上野山怜子对接触过荆芥内酯醇的猫咪进行血液检测,发现它们体内会大量分泌内啡肽。这类激素能够阻断痛觉信号、缓解压力,带来愉悦、镇定的感受。而猫薄荷则是借助一种结构相近的物质——荆芥内酯,同样能刺激猫体内大量释放内啡肽。正是这种快乐激素的迸发,让猫薄荷和木天蓼产生了标志性的、类似药物带来的反应。These compounds don’t just trigger this effect in small cats. When the researchers brought nepetalactol-treated filter paper to a few zoos, leopards, lynxes, and jaguars all dove face-first into the compound. This was big news. If these different cat species reacted to nepetalactol the same way, the response was likely a shared evolutionary trait, potentially something important to cat survival that stretched back millions of years. When the silvervine researchers presented their work at a conference, one evolutionary biologist raised a compelling theory. In chemical terms, both nepetalactol and nepetalactone are classified as iridoids – a type of natural compound known to contain insect-repelling properties. So perhaps cats rubbing their faces in silvervine and catnip were applying an ancient form of bug spray.这类化合物并非只对小型猫科动物生效。当研究人员把滴有荆芥内酯醇的滤纸带到几家动物园时,豹子、猞猁和美洲豹全都一头埋上去嗅闻。这是一项重大发现。既然这么多不同种类的猫科动物都对荆芥内酯醇产生相同反应,说明该行为极有可能是共有的进化特征,或许关乎猫科动物生存的重要本能,其根源可追溯至数百万年前。当木天蓼研究团队在学术会议上展示成果时,一位进化生物学家提出了一个极具说服力的假说:从化学分类来看,荆芥内酯醇与荆芥内酯都属于环烯醚萜类化合物,这类天然物质具备驱虫特性。所以,猫咪把脸在木天蓼和猫薄荷上蹭来蹭去的行为,或许正是在涂抹一种古老的驱虫剂。To test this, researchers set up cages of mosquitoes that cats could stick their heads into. And sure enough, the cats that had been treated with nepetalactol got fewer mosquito bites than the cats in the control group. The same effect was true for the scientists who’d volunteered their arms in solidarity with their feline subjects. These mosquito-repelling properties are currently our best explanation for why cats love silvervine and catnip. But researchers still had one more question: in their state of euphoria, cats tend to vigorously bite, lick, and rub against these plants. But do cats really need to go this crazy to get their bug-repelling effects?为验证这一猜想,研究人员搭建了放有蚊子的笼子,猫咪可以把头伸进笼内。结果证实,体表接触过荆芥内酯醇的猫咪,被蚊子叮咬的次数少于对照组。就连主动挽起袖子、甘愿和猫咪一同参与实验的科研人员,手臂上的叮咬次数也同样大幅减少。目前,这种驱蚊特性是我们解释猫咪喜爱木天蓼与猫薄荷最合理的假说。但研究者还有一个疑问:当猫咪在亢奋状态下,往往会使劲啃咬、舔舐并用力蹭擦这类植物。可它们真的需要表现得如此“上头”,才能真正发挥驱虫功效吗?To investigate rubbing, they provided cats with filter papers treated with microscopic amounts of nepetalactol. And sure enough, even these tiny doses made the papers irresistible, suggesting that microscopic amounts of bug repellent can be transferred by rubbing alone. As for biting and licking, the researchers found that when cats damage the plant, the leaves actually produce more mosquito-repellent chemicals. So your cat isn’t just ripping open their bags of catnip to be annoying; their evolutionary instincts are just trying to get even more of that bug protection.为研究摩擦行为,研究人员向猫咪提供了只沾有微量荆芥内酯醇的滤纸。不出所料,即便剂量微乎其微,这些滤纸依旧对猫咪有着极强吸引力。这说明,仅靠蹭一蹭,就能沾上微量的驱虫物质。至于啃咬和舔舐,研究人员发现,当猫咪啃破植物组织时,叶片反而会生成更多驱蚊化学成分。所以,你的猫咪扒开猫薄荷袋子并不是故意捣乱,而是在进化本能驱使下,想要获取更多驱虫保护。Cats are far from the only animal to use natural plants for purposes like this. Apes swallow scratchy and hairy leaves to dislodge parasites from their guts. Sheep munch on tannin-rich plants to kill intestinal worms, and monarch butterflies use toxic milkweed to kill parasites that normally impair their flight. Just like cats’ ability to find mosquito repellent, these behaviors can help humans identify useful plants and ingredients in the natural world. So, the next time you see your feline friend on a catnip binge, don’t worry – it’s only medicinal.并非只有猫咪会利用天然植物达成这类目的。猿类会直接吞下粗糙多毛的叶片,借此刮擦并排出肠道寄生虫;绵羊会食用富含单宁的植物来杀灭肠道蠕虫;帝王蝶则会采食有毒的马利筋,清除会削弱自身飞行能力的体内寄生虫。和猫咪寻找天然驱蚊植物的本能一样,这类动物行为,也能帮助人类发掘自然界里有价值的植物与成分。所以,下次看到你的猫主子沉迷猫薄荷,不必担心——这只是它在“用药”而已。【词汇】1.stoic adj. 坚忍的;沉着的2.whiff n. 一闻;一股气味3.drool v. 流口水4.wriggle v. 扭动;蠕动5.feline adj. 猫科的;猫的6.euphoria n. 欣快;极度愉悦7.catnip n. 猫薄荷8.painstaking adj. 煞费苦心的;极其仔细的9.dribble v. 使滴下;滴落10.pounce v. 猛扑;突然袭击11.endorphin n. 内啡肽12.lynx n. 猞猁13.jaguar n. 美洲豹14.dislodge v. 驱逐;移开15.munch v. 大声咀嚼16.intestinal adj. 肠的17.milkweed n. 马利筋(一种植物)18.binge n. 狂欢;放纵行为 (本文图片来源于摄图网,版权归摄图网所有)

双语阅读 | 为什么大型AI实验室正在大量招聘哲学家?

为什么大型AI实验室正在大量招聘哲学家?Why big AI labs are hiring so many philosophers?文本难度:CET-6刘立军供稿Ten years ago, as the AI revolution was gathering pace, arts and humanities students were told that, if they wanted to make themselves employable, they should “learn to code”. That may have been bad advice. These days, it is programmers who are nervous about AI taking their jobs.十年前,随着人工智能革命加速推进,文科生曾被告知,如果想让自己更具就业竞争力,就应该“学点编程”。但如今看来,这或许是个糟糕的建议。现在感到焦虑的已换成了程序员——他们担心自己的岗位会被AI取代。They might consider learning to philosophize. Earlier this year the Federal Reserve Bank of New York published figures showing that American philosophy graduates are more likely to have jobs than their peers who studied computer science. In 2024, the most recent year for which numbers are available, 7% of those who had studied computer science were unemployed, against just 5.1% of philosophers.他们或许才该考虑去学学哲学。今年早些时候,纽约联邦储备银行公布的数据显示,美国哲学专业毕业生比计算机科学专业的同龄人更容易找到工作。在数据可查的最近年份——2024年,计算机专业毕业生的失业率达7%,而哲学专业毕业生仅为5.1%。Many are being snapped up by AI firms themselves. Students get job offers before they have graduated, says Luciano Floridi, a philosopher at Yale University. Academics are moving, too. Dr Floridi describes the scale of departures from philosophy departments as a “hemorrhaging”.许多哲学专业毕业生正被AI公司直接抢走。耶鲁大学哲学家卢西亚诺·弗洛里迪表示,很多学生还没毕业就收到了工作录用通知。高校学者也在纷纷出走。弗洛里迪博士将哲学系人才流失的态势形容为一场“大出血”。Some of the lessons that philosophy can offer AI researchers are ancient. The Socratic method—as described by Plato, an ancient Greek philosopher—uses feigned ignorance and sequential questioning to clarify meanings, spot contradictions and reveal ramifications. Many current AI systems tend towards sycophancy. Models trained in the Socratic method, says Jörg Noller, an expert on philosophy and AI at Ludwig Maximilian University of Munich, are less keen on people-pleasing and more willing to pursue the truth.哲学能为AI研究者提供的某些洞见,其实古已有之。古希腊哲学家柏拉图所描述的苏格拉底诘问法,通过“假装无知”和循序渐进的提问,来厘清概念、发现矛盾并推演深层影响。然而,当前许多AI系统都存在一味迎合用户的倾向。慕尼黑大学哲学与AI交叉领域专家约尔格·诺勒表示,若用苏格拉底式方法来训练模型,它们会减少讨好用户的冲动,转而更坚定地追求真相。Philosophical training can also affect a model’s outlook in more specific ways. Feed an AI legal assistant the writings of John Locke, says Thomas Powers, a philosopher of technology at the University of Delaware, and it will favor robust property rights as an underpinning of political liberty. And if you don’t like those principles, the model-makers have others. The “Granite” series of models from IBM, an American computing giant, come with dials that let business customers better align outputs with their own corporate philosophies. Francesca Rossi, IBM’s head of responsible AI, says these can let users choose where to strike the balance between philosophical trade-offs, such as individual agency versus social harmony.哲学训练还能以更具体的方式,塑造模型的价值取向。特拉华大学技术哲学家托马斯·鲍尔斯指出,如果让AI法律助手研读约翰·洛克的著作,它就会倾向于将坚实的财产权视为政治自由的基石。如果你不喜欢这些原则,模型开发者还有其他选择。美国计算巨头IBM推出的“Granite”系列模型配备了调节旋钮,让企业客户能够更好地使输出结果与自身的企业理念相契合。IBM“负责任AI”负责人弗朗西斯卡·罗西表示,这些旋钮可以让用户在各种哲学层面的取舍间把握平衡,例如在“个人自主性”与“社会和谐”之间找到恰当的权衡点。Philosophy can help with safety, too. Researchers have documented all sorts of ominous behavior in AI models, including attempts to evade oversight and even blackmail their users. One way model-makers try to discourage this sort of misbehavior is called AI constitutionalism. This involves building a model around a scaffolding of rules and principles culled from philosophical writings with legal or moral authority.哲学也能在安全领域发挥作用。研究人员记录了AI模型中出现的各种令人担忧的行为,包括试图规避监管甚至勒索用户的行为。为遏制此类不当行为,模型开发者引入一种被称为“AI宪政主义”的机制。该机制要求以一套规则和原则作为底层支撑框架,而这些规范均是从具有法律或道德权威的哲学著作中遴选提炼而成。The biggest question, though, is what sorts of rules should be put in those constitutions in the first place. Philosophers have zeroed in on two main ethical frameworks. One is deontology. Popular with Kant, among others, this imposes strict rules that prohibit things like lying, coercion and treating people as a means rather than an end, even if it is for a greater good. Anthropic’s constitution incorporates many deontological strictures. These can make AI behavior more consistent, says Dr Powers—a plus for deploying robots in homes and public spaces.然而,最大的问题是:这些“宪法”中究竟应该纳入什么样的规则?哲学家们聚焦于两大核心伦理框架。其一是义务论。以康德等学者为代表,该理论强调设定严格的规则,禁止说谎、胁迫或将他人视为手段而非目的等行为,即使此举可能带来所谓的更大福祉。Anthropic公司的“宪法”便纳入了许多义务论式的刚性约束。鲍尔斯博士表示,这类规范可以使AI行为更加一致——这正是在家庭和公共场所部署机器人的重要优势。The other approach to ethics of interest to philosophers of AI is called consequentialism. It weighs costs against benefits to decide what to do. Models more sympathetic to consequentialism include OpenAI’s ChatGPT and Google’s Gemini. Google’s AI models are designed to produce “likely overall benefits [that] substantially outweigh the foreseeable risks”, a classic consequentialist goal.AI哲学研究者关注的另一种伦理方法被称为结果主义。它通过权衡成本与收益来决定该做什么。更倾向于结果主义的模型有OpenAI的ChatGPT和谷歌的Gemini。谷歌的AI模型在设计时明确以“可能带来的整体收益远远超过可预见的风险”为目标——这是一个典型的结果论目标。Consequentialist algorithms are also crucial in software for autonomous vehicles: if an accident is unavoidable, a decision must be made on the least tragic way to crash. Chris Gerdes, a senior engineer at Waymo, which makes self-driving cars, says the trend is to make driving software more consequentialist. Consequentialism is also central to AI weapon systems. Military objectives must be weighed against possible civilian deaths, says Jack Shanahan, a former head of the Joint Artificial Intelligence Centre, which studies AI for America’s armed forces.结果主义算法在自动驾驶汽车的软件中也至关重要:如果事故不可避免,就必须做出决策,以损失最小的方式发生碰撞。自动驾驶汽车制造商Waymo的资深工程师克里斯·格德斯表示,目前的趋势是让驾驶软件更深度地融入结果主义逻辑。结果主义也是AI武器系统的核心原则。曾负责为美军开展人工智能研究的“联合人工智能中心”前主任杰克·沙纳汉表示,必须在军事目标的达成与可能造成的平民伤亡风险之间进行权衡。Thorny problems abound—a philosopher’s favorite sort. Are there cases when deontological rules should be overridden? How do you make decisions when the consequences are unclear? Should AI systems take into account animal welfare, or the state of the environment? Would it be morally acceptable to prioritize young pedestrians over old ones? 棘手的问题层出不穷——正是哲学家最热衷探讨的那类问题。是否存在义务论规则应该被推翻的情况?当后果不明确时,该如何做出决策?AI系统是否应该考虑动物福利或环境状况?优先保护年轻行人而非年长行人,在道德上是否可以接受?Critics fret about “moral deskilling”: if computers increasingly make ethical calls, might people become less willing to make their own judgments? Roman Yampolskiy, an AI theoretician at the University of Louisville, argues that morality “is historically unstable, culturally variable, strategically manipulable, and often only retrospectively legible”. Unemployed coders take note: there seems to be no shortage of work for philosophers of AI.批评者担忧“道德能力退化”:如果计算机越来越多地做出伦理判断,人们是否会逐渐丧失自己做判断的意愿?路易斯维尔大学的AI理论家罗曼·扬波尔斯基认为,道德“具有历史的不稳定性、文化的可变性与策略的可操纵性,而且往往只能事后追溯其意义”。失业的程序员们请注意:AI哲学家的饭碗恐怕永远不缺。【词汇】1. humanities n. 人文学科;人文科学2. hemorrhage n. 大量流失(文中喻指人才流失)3.

双语阅读 | 推行禁烟竟如此艰难

推行禁烟竟如此艰难It’s Maddeningly Difficult to Ban Smoking文本难度:六级(CET-6)刘立军供稿The U.K.’s landmark generational cigarette ban, which received royal assent in April 2026 and is due to take effect in January 2027, might yield its most dramatic results decades from now, if it sticks around that long. 英国具有里程碑意义的代际禁烟法案于2026年4月获得王室批准,并将于2027年1月正式生效。英国新近出台的禁烟令若能持续落地执行,或许要在数十年后才能显现出最显著的效果。Since tobacco first arrived on the shores of England in the late 16th century, some Brits have wanted to eradicate it. Back in 1604, King James I was so alarmed about his country’s new smoking habit that he imposed a 4,000 percent tariff on the crop. That year, he wrote one of the world’s first anti-tobacco essays, declaring smoking “loathsome to the eye, hateful to the nose, harmful to the brain, dangerous to the lungs.” 自16世纪末烟草传入英国起,就有部分英国人希望彻底根除烟草。1604年,詹姆斯一世国王就对国内兴起的吸烟风气深感忧虑,于是对烟草征收税率高达4000%的关税。同年,他撰写了世界上最早的反烟草论著之一,称吸烟“触目生厌、刺鼻难闻、损伤大脑、戕害肺腑”。Despite the best efforts of the king and the generations of anti-tobacco activists who followed him, people in the United Kingdom still smoke. Now advocates are hoping a new law that prohibits anyone born on or after January 1, 2009, from ever buying cigarettes will finally end the habit for good. But the tobacco-free generation, at least in the short term, is unlikely to truly be tobacco-free. 尽管英国国王以及后世一代又一代反烟草人士竭尽全力,很多英国人至今仍在吸烟。如今,支持控烟的人士寄希望于一项新法案:该法案禁止2009年1月1日及以后出生的人购买香烟,期盼以此彻底终结这一恶习。然而,至少在短期内,这个所谓的“无烟一代”,恐怕难以真正做到完全不接触烟草。Generational tobacco bans were first proposed in 2010 by a group of researchers in Singapore. Around that time, less extreme anti-tobacco measures — such as media campaigns, clean-air laws, and taxes — had reduced smoking in many countries to such a point that public-health advocates started to seriously consider policies that could shrink rates to effectively zero. A tobacco “endgame,” as it has become known, was in sight. “I want to stamp out smoking for good,” Rishi Sunak, the former U.K. prime minister, said in a statement when he first proposed the plan in 2023. 2010年,新加坡的一个研究团队首次提出了“代际禁烟令”这一构想。当时,媒体宣传、清洁空气法案、烟草税收等相对温和的控烟措施,已将许多国家的吸烟率降至较低水平。公共卫生领域的倡导者由此开始认真研究,思考如何通过采取更为彻底的政策,将吸烟率降至接近于零。业界所说的烟草管控“终局”似乎近在眼前。2023年,英国前首相里希·苏纳克在首次提出该方案时发表声明称:“我希望彻底根除吸烟现象。”Currently, U.K. residents need to be 18 or older to purchase cigarettes. The new generational ban will introduce a more unusual paradigm: Beginning on January 1, 2027, an 18-year-old born on New Year’s Day 2009 will not be able to buy products such as cigarettes and chewing tobacco for the rest of their life. But a friend born one day earlier would face no such barrier. That means, as some critics of the ban have pointed out, that 18-year-olds will almost certainly bum cigarettes from older friends — the same way younger teens have acquired them since time immemorial. Data suggest that most adolescent British smokers get cigarettes for free from older people they know. In one study, in which researchers interviewed British smokers as young as 12 about how they obtained cigarettes, kids who waited outside of tobacco shops in hopes that an older customer would buy for them reported mostly targeting people under 25. 目前,英国居民需年满18周岁才可购买香烟。而这项全新的代际禁令将带来一种更为特殊的管控模式:自2027年1月1日起,2009年元旦出生的青年,即便年满18岁,终身都不得购买香烟、嚼烟这类烟草制品。但如果有人仅早一天出生,则不受这条禁令限制。正如该禁令的部分批评人士所指出的,这意味着这批年满18岁的年轻人几乎肯定会向年龄更大的朋友讨要香烟——古往今来,低龄青少年就是这样获取香烟的。数据表明,英国绝大多数未成年吸烟者,都是从相熟的长者手上免费拿到香烟。在一项针对低至12岁的英国吸烟青少年的研究中,研究人员询问了他们获取香烟的途径。部分青少年会守候在烟草店门外,指望年长顾客帮忙代买,据他们反馈,自己主要找25岁以下的成年人帮忙。Lawmakers included language in the bill designed to dissuade older people from buying cigarettes for their underage acquaintances. But, more importantly, that issue will likely work itself out over time. By 2034, no one under 25 will be able to purchase cigarettes. And with each passing year, kids’ sources of illegal cigarettes should progressively dwindle. Because having peers who smoke increases young people’s chances of starting themselves, fewer kids being able to get their hands on cigarettes should have a ripple effect, dissuading more and more of their peers from experimenting. By 2079, no one under 70 will be legally able to smoke. It will become the habit not of teenage rebellion but of retirement homes. 立法者在法案中增设相关条款,意在劝阻年长者不要为未成年熟人代买香烟。但更重要的是,这一问题大概率会随着时间的推移而自然化解。到2034年,25岁以下的人都将无法购买香烟。年复一年,青少年获取非法香烟的渠道也会日益萎缩。身边有吸烟的同龄人,会增加年轻人开始吸烟的概率;能够接触到香烟的青少年越来越少,将会产生连锁反应,促使更多同龄人打消尝试吸烟的念头。到2079年,70岁以下人群将不再具备合法吸烟的资格。吸烟将不再是青春期叛逆的标志,反倒会成为养老院里的一种习惯。This all depends, of course, on retailers actually following the law — a big if, according to some tobacco-control experts I spoke with. In a 2023 NHS survey, one-third of youth smokers reported regularly (and illegally) buying cigarettes from shops. “I don’t think we should play down the need for enforcement,” Nathan Davies, a doctoral fellow at the University of Nottingham who studies tobacco control, told me. And even if shopkeepers play by the rules, other people might not. Consider the small Himalayan nation of Bhutan, where all tobacco sales were banned in 2004, but cigarettes remained easy to access because a black market quickly cropped up. Those dealers didn’t serve just existing smokers but also young children. In 2019, nearly a quarter of 13-to-15-year-olds in the country used tobacco. 当然,这一切的前提是零售商能否真正遵守法律——我采访的一些控烟专家称,这还是个巨大的未知数。英国国家医疗服务体系(NHS)2023年的一项调查显示,三分之一的青少年吸烟者称自己经常(且非法地)在商店购买香烟。诺丁汉大学从事控烟研究的博士研究员内森·戴维斯表示:“我们绝不能弱化执法的重要性。”即便商家恪守规定,其他人却未必照做。以喜马拉雅山区小国不丹为例:该国2004年全面禁止烟草销售,但黑市迅速滋生,香烟依然极易获取。这些黑市商贩不仅向吸烟人士供货,甚至把魔爪伸向了青少年。2019年,该国近四分之一的13-15岁青少年使用了烟草制品。Nigel Farage, the leader of the right-wing Reform U.K. Party, has repeatedly insisted that such a black market could appear in the U.K. too. But the country’s experiment was not technically a generational tobacco ban, unlike the policy in the U.K., which was crafted to ensure that most current smokers can continue to buy their products legally, thus shrinking the profitability of any black market. The Bhutan and U.K. policies are “structurally so different in scope, sequencing, enforcement infrastructure, and market context that the comparison generates more confusion than insight,” Kashish Aneja, who leads initiatives in Asia at Georgetown University’s O’Neill Institute for National and Global Health Law, told me via email. 英国右翼改革党领导人奈杰尔·法拉奇一再提出,英国同样可能滋生这样的黑市。但严格来说,不丹的管控尝试不同于英国的代际禁烟令;而英国出台的这项政策,充分保障大多数现有吸烟者仍可合法购买烟草制品,以此压缩黑市的获利空间。乔治城大学奥尼尔国家与全球卫生法研究所亚洲区项目负责人卡希什·阿内贾在邮件中指出,不丹与英国的政策“在管控范围、实施节奏、执法配套体系以及市场环境上存在本质结构性差异,将两者进行比较,更多只会造成认知混淆,而无法带来有效借鉴”。No actual generational tobacco ban has existed for enough years to reveal its long-term effects. The Maldives, a small island nation south of India, implemented such a policy in November. Several Massachusetts towns have also passed similar bans. Brookline, a wealthy suburb of Boston, was the first, enacting its own version in 2021. Available data suggest the ban has had little effect on cigarette smoking thus far, but according to advocates, real change will take much more time. “It is a slow and gentle policy change which will result in changes over the mid and long-term,” Mark Gottlieb, the executive director of the Public Health Advocacy Institute at the Northeastern University School of Law, told me in an email. 迄今为止,还没有任何真正落地的代际禁烟令已经过足够长的时间来验证其长期成效。位于印度以南的岛国马尔代夫于去年11月实施了同类政策。美国马萨诸塞州的几个城镇也通过了类似禁令。而波士顿的富裕郊区布鲁克莱恩则走在了前列,于2021年在当地开始实施禁令。现有数据表明,该禁令迄今为止对吸烟行为的抑制作用微乎其微,但支持该政策的人士表示,实质性改变需要更长的时间。东北大学法学院公共卫生倡导研究所执行主任马克·戈特利布在给我的邮件中写道:“这是一项温和渐进的政策,其成效将在中长期逐渐显现。”New Zealand’s left-wing Labor Party passed a tobacco-free-generation policy in 2022. But the country’s new center-right coalition government, on taking power in 2024, repealed the law before it went into effect. The government’s stated reasons for the repeal were so that cigarette-tax revenue could pay for a slew of new tax cuts, and because it was argued that the policy would have fueled illegal smuggling. Something similar might happen in the U.K. Farage, himself a smoker, has called the ban “puritanical” and vowed to repeal it if his party takes power. 新西兰左翼工党于2022年通过了“无烟一代”政策。但该国新一届中右翼联合政府2024年上台后,在法案生效前就将其废除。政府给出的废除理由有两点:一是需要依靠香烟税收,支撑一揽子减税政策;二是认为该政策会助长非法走私活动。类似的情况也可能在英国上演。本身就是吸烟者的法拉奇,称这项禁令带有“清教徒式的禁欲色彩”,并扬言若其政党上台执政,必将予以废除。He’s probably not the only one who’d like to see that happen. Tobacco companies urged Parliament not to pass the law, arguing that it was discriminatory and would not prevent youth smoking — and would increase crime, to boot. “Every year from 2027 onwards a generational ban will hand more of the UK tobacco market to the serious organized criminal groups who will use the proceeds of illegal tobacco to fund activities including terrorism, weapons trading, the distribution of narcotics and people smuggling,” Japan Tobacco International, which owns a number of the most popular cigarette brands in the U.K., wrote. (In a statement, a JTI spokesperson added to that list, writing, “Illegal tobacco in the UK has been linked to organized crime, including activities such as money laundering, human trafficking, and violence.”) The tobacco industry, along with smokers’-rights groups, also aggressively courted certain U.K. conservatives as the new ban was being debated, hosting them for lunches and at least one party. 希望看到禁令被废除的恐怕不止法拉奇一人。烟草公司曾游说议会否决该法案,称其具有歧视性,不仅无法阻止青少年吸烟,还会加剧犯罪。拥有英国多个畅销香烟品牌的日本烟草国际公司(JTI)写道:“自2027年起,代际禁烟令会逐年把英国更大一部分烟草市场拱手交给大型有组织犯罪集团。这些团伙将利用非法烟草的利润,资助恐怖主义、武器交易、毒品贩运、人口走私等各类犯罪活动。”(JTI发言人在另一份声明中补充道:“英国境内的非法烟草贸易与洗钱、人口贩运和暴力等有组织犯罪活动密切相关。”)在新禁令的辩论期间,烟草行业还联合吸烟者权益组织积极拉拢部分英国保守派议员,为他们举办午餐会,以及至少一场社交派对。Despite the debate, generational smoking bans are broadly popular. A poll commissioned by the anti-smoking group Action on Smoking and Health found that 68 percent of English people support the new ban. In New Zealand, about 60 percent of voters opposed the country’s about-face. Perhaps that’s because smoking remains one of the world’s leading causes of preventable death, or because the overwhelming majority of smokers regret ever starting. The new policy might not make much difference for today’s teens, but decades from now, a new generation really might avoid that lifelong error — as long as the ban actually sticks around. 尽管争议不断,代际禁烟令仍广受民众欢迎。反吸烟组织“吸烟与健康行动”委托开展的民调显示,68%的英格兰民众支持这项新禁令。在新西兰,约60%的选民不认同禁烟政策的彻底转向。究其原因,可能是因为一方面吸烟依然是全球可预防死亡的首要诱因之一,另一方面绝大多数吸烟者对当初染上烟瘾后悔不已。这项新政策或许不会对今天的青少年产生太大影响,但几十年后的那一代人真的有可能避免犯下这个终身错误——前提是这项禁令能够切实长期推行。【词汇】1. time immemorial 太古时代,很久以前2. dissuade v. 劝阻;阻止3. dwindle v. 逐渐减少;缩小4. ripple effect 连锁反应5. doctoral adj. 博士的6. repeal v. 废除;撤销7. a slew of 大量;许多8. narcotic n. 麻醉药;毒品9. trafficking n. 非法交易,非法买卖10. publicize v. 宣传;宣扬11. proponent n. 支持者;倡导者12. about-face n.

TRANSCRIPTVaccines: Science vs. ScareVGS: We’re standing here in front of the statue commemorating the smallpox eradication campaign. (Q1) Smallpox being the only disease that the world, humanity, has eradicated. This WHO-led campaign was the first mass vaccination campaign that brought together countries, experts and communities. Today, we have 30 vaccines that can prevent many many diseases. And 154 million lives have been saved, in the last 50 years, by just 14 of those vaccines. So if you’re a new parent, you may have questions about vaccines. We have Doctor Kate O'Brien here with us to answer your questions. Kate, let’s start with — parents may have heard what if we let our child get sick and develop immunity rather than vaccinate them? What is your advice regarding that?smallpox n. 天花 vaccinate v. 接种疫苗 KOB: The first thing I want to say is that the vaccines that have been developed that are in our program, are vaccines against serious diseases. Sometimes we hear the term natural immunity. And I really want to address this question. (Q2) Some people think that getting infected is somehow more natural than it is to develop your immunity from a vaccination. And I really want to disavow this. It’s the immune system in either circumstance is responding to either a germ or the vaccine itself. What’s most important is that exposing children to infections and risking the consequences of serious disease, and in the worst circumstances, death, is not what any parent would want to do.disavow v. 否认,拒绝承认 VGS: Another question that young parents may have is if you give a child many vaccines at the same time, you might overwhelm their immune system. What would you say to that?KOB: (Q3) Children are exposed to, in fact, millions of different microbes in the natural environment around us, in their foods, in the environment, by touching things, in their own bodies. We all have, in fact, more microbes in our body than we do human cells. This is an important way that children’s immune systems develop. The issue is, how to allow children to develop immunity against those germs that are consequential, that are serious, that cause disease. So the point around the vaccines is, children’s immune systems are more than able to respond to multiple vaccines, given at the same time, and multiple doses that are given over the course of their lifetime. Although we perceive that they’re being given “a lot of vaccines” in fact, on a daily basis, children are being exposed and sampling that outside world of those microbes all the time. The immune system is an incredibly powerful system. It’s amazing the way that it matures and identifies which is friend and which is foe in the environment. And vaccines are the safest way to actually derive protection for children, adolescents and adults against the consequential germs.consequential adj. 重要的,意义重大的 VGS: Can parents maybe stagger the schedule? Give a little space? Would that still have the same impact that you are seeking in protecting the child?KOB: Yeah. So this seems like a common sense, logical thing to do. We have studies that tell us in what sequence the vaccines should be given, how many doses should be given and how far apart they should be. Now, when you mess around with that schedule, there are consequences of doing that. First, it means that children may miss the doses that they should get. Second, it means that they may not get the vaccines at the time when they most need them. (Q4) We time the schedule so that the protection is developed before the period of time when children are most at risk of the particular disease that the vaccine is protecting against. And third, there are some vaccines that need to be timed relative to other vaccines that are in the schedule. They don’t work as well if they’re timed incorrectly. So that’s the reason why we have pediatricians, scientists, epidemiologists who make the recommendations within each country for what the schedule should be.VGS: So WHO makes a recommendation, right? But who is deciding on what vaccinations a citizen receives?KOB: Countries are the ones who decide on their schedule. What WHO does is, because we’re a global recommending body, we pull together experts from around the world. We ask them to look at all of the evidence that is available and we provide recommendations to countries. They can rely on the aggregated evidence that we’ve put together, so they can also deliberate on what makes most sense for their particular circumstance.VGS: Thank you Kate. I have additional questions. I’m sure our viewers have additional questions. So we will take this in part two where we will answer some of your questions on vaccines. Until next time then, stay safe, stay healthy and stick with science.Part III. KEYQ1. B.【解析】细节题。根据“Smallpox being the only disease that the world, humanity, has eradicated.”, 此句明确指出天花是人类唯一消灭的疾病,因此正确答案为B。 Q2. C.【解析】细节题。根据“Some people think that getting infected is somehow more natural than it is to develop your immunity from a vaccination… It’s the immune system in either circumstance is responding to either a germ or the vaccine itself.”,该句说明无论是自然感染还是接种疫苗,免疫系统都会对外来病菌产生反应,因此正确答案为C。 Q3. A.【解析】推理题。根据“Children are exposed to, in fact, millions of different microbes in the natural environment around us, in their foods, in the environment, by touching things, in their own bodies.”,此处说明孩子在日常环境、食物、身体中时刻接触数百万微生物,免疫系统长期接触各类细菌,因此可以推断正确答案为A。 Q4. C.【解析】细节题。根据“We time the schedule so that the protection is developed before the period of time when children are most at risk of the particular disease that the vaccine is protecting against”,该句明确指出安排疫苗接种时间是为了在儿童高危阶段前建立防护,因此正确答案为C。 Q5. B.【解析】主旨题。文章主要围绕疫苗对儿童的重要性以及父母对疫苗的常见顾虑展开,专家逐一破除误区、解答疑惑,因此正确答案为B。 (本文图片来源于摄图网,版权归摄图网所有)

It relies solely on clinical trial data for safety evaluation. B. It prevents people from reporting unrelated issues. C. It identifies patterns from millions of submitted reports. D. It stops monitoring once vaccines are approved. Part II. TRANSCRIPTThe truth about vaccine safetyVGS: We are talking about vaccine today. This is part two of the vaccine series of Science in 5. In the first part, we spoke about some concerns that parents may have. (Q1) And in this video we are going to talk to our expert, Dr Kate O’Brien, about the ingredients of the vaccine. How do we make sure that vaccines are safe? Let’s start with the ingredients of the vaccine. There’s a lot of information and even misinformation out there. So please unpack this for us.KOB: So I want to just go through a couple of them because they have, you know, words and names that are pretty unfamiliar in our kind of day to day lives. And I think for a lot of people it can be concerning. For some it might sound a bit scary in some way. Many of the ingredients are actually components that we have in our environment, or in our foods. Not all the components of vaccines are foreign to our bodies or our exposure. So some of the ingredients include antigens. (Q2) Antigens are the part of a germ that is the actual part we want the body to develop its immunity to. It helps the immune system to actually recognize that foreign invader, that foreign germ that’s going to potentially cause disease. Second, are adjuvants. And adjuvants are the part of the vaccine that help boost the immune system. Not all vaccines will result in an adequate immune response without an adjuvant. The third part that’s added to a vaccine are maybe we can call them stabilizers. (Q3) And these are things that make sure that the vaccine is safe during transport and during all of the moving of the vaccine around. We also have, components of the vaccine that allow for some vaccines to be used after the vaccine vial is opened. If that’s made with multiple doses in a vial, it needs to be safe to keep that vaccine for multiple days in the refrigerator so that the next child who comes in can receive an additional dose in the vaccine.adjuvant n. 佐剂,助剂 vial n. 小瓶,药瓶 VGS: So let’s talk about the safety of the vaccine. That’s a concern a lot of parents may have. There is certainly a lot of information and misinformation about it outside. Talk to us about how we ensure that vaccines are safe. What is that process that vaccines are put through before they come to market?KOB: The very first thing that happens is that when a vaccine is being developed in the clinical trials, safety is monitored extremely carefully on a day to day basis, among those who have received the vaccine. There are phone calls made, logs filled out by parents about exactly what’s happening to this child. In order for a vaccine to go from a clinical trial to actually being an approved vaccine all of that safety information is rigorously evaluated, and it is assessed by experts who determine whether or not it needs safety standards. After a vaccine has been approved by a health authority the safety monitoring does not stop. In fact, safety monitoring goes out for the whole lifetime of use of a vaccine. It never actually stops. So health authorities are monitoring whether any reports are being given about potential problems with a vaccine. (Q4) Now at WHO, we have a safety committee. It’s an external committee of experts. And they get together and they review the reports that are submitted to the Global Monitoring Center. This is called the Global Advisory Committee on Vaccine Safety. And if a new safety issue comes up, we will issue a report around that safety issue.rigorously adv. 严厉地;严密地 VGS: So let’s talk about it when, there are concerns about the safety or there are concerns about a vaccine. What happens next?KOB: So what’s really important for people to understand is how this system works. It doesn’t mean anything to actually be telling the world how many reports came in, because you could submit a report about something that has absolutely nothing to do with the vaccine. That’s why the system is completely open, we don’t want to put any barriers up to people being able to report. What’s done with all of those reports is a careful review of them, especially in relation to which vaccines the report says were received and to see if there are any patterns that start to emerge in the reports. (Q5) If there starts to be a signal that comes up from those many, many, in fact, millions of reports that are sent in, we look into that signal specifically with the kinds of studies that will determine, is this something that is actually related to the vaccine or not related to the vaccine?VGS: Thank you Kate for explaining that. Those were some of the questions that we knew people had about vaccines. If you have more questions, put that on our timelines and tell us if you want us to continue explaining, clarifying any of your concerns about vaccines. Until next time then, stay safe, stay healthy and stick with science.Part III. KEYQ1. D.【解析】细节题。根据“Antigens are the part of a germ that is the actual part we want the body to develop its immunity to. It helps the immune system to actually recognize that foreign invader, that foreign germ that’s going to potentially cause disease.”,可知抗原的功能是帮助免疫系统识别外来病原体,因此正确答案是D。 Q2. A.【解析】细节题。根据“And these are things that make sure that the vaccine is safe during transport and during all of the moving of the vaccine around.”,可知稳定剂的主要功能是确保疫苗在运输和移动过程中保持安全有效。因此正确答案是A。 Q3. B.【解析】细节题。根据“And they get together and they review the reports that are submitted to the Global Monitoring Center. This is called the Global Advisory Committee on Vaccine Safety. And if a new safety issue comes up, we will issue a report around that safety issue.”,可知世卫组织的全球疫苗安全咨询委员会负责监控疫苗的安全性,并在发现新的安全问题时发布相关报告,也就是说该委员会的职责是全程监控疫苗的安全性,因此正确答案是B。 Q4. C.【解析】推理题。根据“If there starts to be a signal that comes up from those many, many, in fact, millions of reports that are sent in, we look into that signal specifically with the kinds of studies that will determine, is this something that is actually related to the vaccine or not related to the vaccine.”,可知如果从那些实际上提交的数百万份报告中开始出现一个信号,监控系统会专门通过研究来分析该信号,以确定它是否与疫苗相关。这表明监控系统通过分析大量报告来识别潜在问题,因此正确答案是C。 (本文图片来源于摄图网,版权归摄图网所有)

What is the main purpose of the text? A. To discuss strategies for building and maintaining long-lasting habits. B. To explain why SMART goals are essential for habit formation. C. To highlight the importance of willpower in achieving goals. D. To emphasize the role of spontaneity in daily routines. Part II. TRANSCRIPTSmall steps to build long-lasting habitsIt’s day one of a healthier, smarter, better you. You’re full of zest and good intentions. You woke up at 5am to run before work, you read a book in your lunchbreak, and you listened to an English podcast on your commute. Now, fast forward three months. Life is getting in the way, and you’ve slipped into old habits… snoozing your alarm and eating chocolate for breakfast. Sound familiar?zest n. 热情,兴趣 podcast n. 播客,音频节目 commute n. 通勤,往返于工作地点和住所之间 Don’t be hard on yourself. It’s unrealistic to rely on willpower alone. (Q1) As James Clear, author of the bestselling book Atomic Habits, writes, “The problem isn’t you. The problem is your system.” Our habits come from goals, so start by getting really clear. Goals, according to George T Doran, should be SMART: specific, measurable, achievable, relevant and time-bound. It’s not enough to say, “I’ll exercise more” – that’s too vague! (Q2) A SMART goal would be “I’m going to walk for 20 minutes in the evenings on weekdays.” Now you have a clear action that you can stick to.vague adj. 模糊的,不明确的 Once you’re clear on your goals, you need to make the associated habits as automatic as possible. (Q3) Try ‘habit stacking’, a technique popularised in the book Atomic Habits, which involves attaching a new habit onto something you already do regularly. For example, if you already make coffee every morning, use that moment to read your book for 20 minutes. That way, your new reading habit is now intertwined with something you’re going to do anyway. Another key strategy is to reward yourself, to transform the habit from a chore into something pleasurable. If it’s hard to get yourself to the gym, promise yourself that after each visit, you’ll allow yourself a treat – a takeaway meal or an episode of your favourite TV show.stack v. 堆叠,堆积 (Q4) Even with our best intentions and a great system, stress and interruptions to your routine like social events can still make keeping habits feel like an uphill battle. If or when you have setbacks, accept it as part of the process. Life is full of spontaneity and uncertainty – one could argue that’s what keeps it interesting! Use setbacks as a pause for reflection and review. What about your system is working? What’s no longer serving you? Then, get back on track.spontaneity n. 自发性,自然性 Part III. KEYQ1. C.【解析】细节题。根据“As James Clear, author of the bestselling book Atomic Habits, writes, “The problem isn’t you. The problem is your system.” ”,可知詹姆斯·克利尔认为,人们无法坚持好习惯,问题不在于人本身,而在于自身的体系存在缺陷。因此正确答案为C。Q2. B.【解析】细节题。根据“A SMART goal would be “I’m going to walk for 20 minutes in the evenings on weekdays.””,可知一个SMART目标可以是“我打算在工作日的晚上步行20分钟。”因此正确答案为B。Q3. D.【解析】细节题。根据“Try ‘habit stacking’, a technique popularised in the book Atomic Habits, which involves attaching a new habit onto something you already do regularly.”,可知habit stacking是指“习惯叠加”,即将一个新习惯附加到你已经经常做的事情上。因此正确答案为D。Q4. B.【解析】推理题。根据“Even with our best intentions and a great system, stress and interruptions to your routine like social events can still make keeping habits feel like an uphill battle. If or when you have setbacks, accept it as part of the process.”,可知即使我们有最好的意图和很好的系统,压力和社交活动等对日常生活的干扰仍然会让保持习惯感觉像是一场艰难的战斗。在培养习惯的过程中遭遇挫折是过程的一部分。因此正确答案为B。Q5. A.【解析】主旨题。整篇文章的核心内容是讨论如何通过明确目标、习惯叠加和奖励机制等策略来建立和维持长期的习惯。“Small steps to build long-lasting habits” 的标题以及文章内容都围绕这一主题展开,因此正确答案为A。(本文图片来源于摄图网,版权归摄图网所有)

第12届教学大赛商务英语组二等奖贺静授课

授课点评:贺静老师授课效果较好,教学目标清楚、教学方法得当、教学程序井井有条。此外,贺静老师口齿清晰,语音语调比较纯正、流利;教态端庄自然,有亲和力,教学过程中与学生互动良好,体现了以学生为主体,教师为主导的教学原则。授课分两部分。第一部分介绍该单元(Empire of Wealth)的总教学安排,用了3分30秒,时间把握得比较好。另外,设计的PPT形式多样,各种图表清楚展现了教学安排。授课开始的第三分钟,PPT显示的该单元总教学目标及三篇课文的教学目标一览无遗,加上贺静老师的阐释,清晰地传递了教学目标和学习目标,这能帮助学生在课堂内外围绕主题有效学习。紧接着,贺静老师借助PPT上的流程图比较详细地介绍了授课课文In Praise of Competitive Urges的教学安排,其中的Problem-centred教学方法对学生发现、分析和解决问题有很大帮助。之后进入第二部分:比赛授课阶段。第二部分具体授课含四个阶段。进入第一阶段Warm-up时,贺静老师显得有点紧张,但很快就调整好了状态。该阶段有教师对课文理解的提问,请学生从课文中找到相关的依据回答问题,这种做法本来值得称道,因为授课不能离开课文。但是,Warm-up阶段是课前准备阶段,因此,贺静老师在Warm-up阶段讲解课文不妥,建议把重点放在教材中的Warm-up Activities上,适当设计一些附加的活动,才符合教学逻辑。此外,在总时间为20分钟且第一阶段用了3分30秒的情况下,Warm-up阶段用了5分1秒显得有点过长。之后是第二阶段Questionnaire Results,贺静老师分析解释了调查表中的信息,谈了自己对问题的看法,期间激励学生思考、回答问题,这对培养学生的独立思考能力及理解课文非常有益。Questionnaire之后进入授课第三阶段:Wealth-flaunting Motivations / Summarizing。炫富动机是课文包含的核心内容之一。因此,讨论炫富动机有助于学生理解课文。教师要求学生从PPT上(视频13')显示的课文段落寻找答案,并要求学生做pair work找到有关的词汇。另外,通过分析课文的修辞寓意,贺静老师阐释了文章作者的真实目的。这一点做得很好。另一方面,根据该单元内容,所授的是“综合商务英语”课程。因此,贺静老师应更多围绕语言难点、篇章结构、写作风格、文法修辞等方面进行解释,让学生对课文有更深层次的理解。第四阶段Assignment在视频18'15"开始。课后作业包括questionnaire设计、调研报告写作、相关阅读作业。这样较好兼顾了综合商务英语课程语言学习和商务实践的教学特点。建议更多以教材内容教学为主,重视语言、篇章教学,在帮助学生充分理解课文的前提下掌握一些商务知识和技能;需要结合课文融入更多的思政教育内容。点评专家:翁凤翔

第12届教学大赛商务英语组特等奖潘紫萌授课

授课点评:潘紫萌老师在本次大赛中与来自全国各地的商务英语优秀教师展开激烈角逐,在教学理念、教学方法、课堂设计、英语素质、商务知识、教姿教态、师生互动等方面的表现都较突出,最后以总分第一荣获特等奖。潘老师以准确的英语发音先声夺人,丰富的表达方式、适中的语调语速和端庄的教姿教态也令人印象深刻。在课程设计环节,为实现其教学目标,她选择business ethics作为主题,介绍了教学目标、学生特征、以学生为中心和以产出为导向的教学理念,以及线上线下结合、传统和高科技媒体结合等丰富多彩的教学方式。这份介绍全面立体但简明扼要,为后面的演示(demo)课提供了一个很好的支撑。由于大赛的授课时间有限,潘老师突出重点,在演示课上只展示教学方案的第三步,即participatory learning 1 和 post assessment 1。她采用BOPPPS(bridge in, objectives, pre-assessment, participatory learning, post assessment, summary)模型,通过德国大众汽车减排作假、中国支付宝公益植树项目等案例,教学目标涵盖商务英语知识、技能、以及相关的伦理和价值观等。在短短的十几分钟里要达到这么多项教学目标绝非易事。潘老师通过一系列的短视频、多种教学方法(如听力填空、案例讨论、汉译英、样本对话补正等)以及活泼的师生互动,较好地实现了教学目标,显示出选手突出的课堂组织能力。商务英语教学起源于英美等国,因此基本使用本国素材、讲本国故事。传入中国后,主要使用外国素材、讲外国故事。令人欣喜的是,潘老师注意突出中国特色,多次引用中国案例,讲授中国故事,传播中国价值观。加上她出色的英语基本功和良好的师生互动,使得教学过程十分流畅,也没有不同文化同场展示的违和感。总而言之,潘紫萌老师在授课环节的各方面表现都很优秀。不足之处当然也有。首先, 8’13’’开始的讨论过于仓促,只有18秒, 8’31’’就结束了。由于讨论不充分,在随后的问答环节中,更多的回答似乎来自老师而不是学生。第二个是要增加教学过程的自然自发 (spontaneity)。不知是因为课前多次排练还是老师特意要求,学生的产出只有一次对话(17’40’’)相对自然,其他的多次回答虽准确无误,但都像中国小学生朗读课文或回答问题,语音、语调、语速都过于整齐合一,这不利于培养学生的英语实际表达能力。点评专家:陈准民
